The results of the survey of millions of people found genetic variations associated with educational levels.

An international team of scientists has launched a survey of 1 million people and found genetic variants associated with educational levels, according to a large genetic study published online Wednesday in the British journal Nature Genetics.
they found more than 1,200 related genetic variants in a large sample, more than ten times the number of gene sites previously found.
the candidate genes in the study have been shown to play an important role in brain development and neuronal communication.
the "status" of some genetic variants is important and affects people's thinking, learning skills and personality traits.
but can a person's genes directly affect how far a person goes on his or her way to education? The debate on this issue has a long history.
Daniel Benjamin of the University of Southern California and a team of international scientists found in an earlier study that multiple genes in the bodies of those with higher levels of education were mutated compared to those with lower levels of education.
scientists still don't know the specific impact of the overall environment, genetic factors on educational attainment, and the potential mechanisms of their effects.
, an international team of scientists from the University of Southern California, the Free University of Amsterdam and the University of Queensland in Australia examined the genetic makeup and educational backgrounds of more than 1 million people.
in large-sample studies, the team found more than 1,200 genetic variants associated with length of education.
the team also analyzed each subject's test scores, self-reporting math skills, and the highest level of math education, and identified hundreds of genes associated with these traits.
analysis found that educational-related genetic variants first appeared in the core regions that control brain development, and that the expression levels of the associated genes increased in the brain, also playing a role in neurotransmitter secretion and synaptic plasticity.
researchers believe that this large pool of related gene sites could be used further to study the effects of gene and environmental interactions on cognitive phenotypes.
